On suggestion of Anatoly Pugachev, I tried util-linux "make check" on some of my older Suns:
E250 with dual UlatraSparc II and Blade 100 with UltraSparc IIe. Both have old 32-bit
userspace from 2015 (inluding gcc 4.9.3) but new kernels from git (5.3-rc4 in both machines).
The util-linux hang was reproducible on both of them, therefor it is not
specific to newer CPU models and MMU-s, and not specific to newre gcc.
On single-CPU Blade 100, the machine became unusable. On dual-CPU E250, one CPU was stuck
and the other worked.
The test that was causing the problem was "fincore: count file contents in core".
The command line of the test was "/bin/bash /home/mroos/util-linux/tests/ts/fincore/count --srcdir=/home/mroos/util-linux --builddir=/home/mroos/util-linux --parallel"
and the script created a subprocess dd that hangs in D state in both servers.
I have full dmesg from the dual CPU machine. After the hang, there are a couple more
"BUG: Bad page state in process lsblk" errors but seem to have not caused a hang.
Is there anything else I can provide - unstripped kernel image or something?
